MACHINE FOR CUTTING CORKS.

SPECIFICATION forming part of Letters Patent No. 601,&92, dated Aprl 5, 1898.

Applioation filed March 31, 1897.

To all whom 't may concern:

Be it known that I, J ULIUS J ONSON, of the city and County of New York, in the State of New York, have invented a new and useful Improvement in Machines for Cutting Corks for Bottles or other Vessels, of which the following is a specification.

In a machine embodying the present invention the raw cork, which has been previously cut into the form of strips or sticks, is placed` in that form in revolving chucks arranged in an intermit tently-rotating carrier by which each of the said chucks in. its turn is first brought opposite a cutter for the purpose of having the end of the stick within it turned or trimmed to the form of a cork and is afterward brought opposite a grinder for the purpose of giving the so turned or trimmed portion a finished surface and is finally presented to a saw or rotary cutter, by which the portion of the stick so shaped and finished is cut off in the condition of a finished cork ready for use. I

The improvement consists in the several combinations of rotary carrier, chucks, cutters, grinder, and Operating mechanism i1lus-` trated by the accompanying drawings and hereinafter described and claimed.

Figure 1 represents a front end elevati on of a machine embodying my invention; Fig. 2, a rear end elevation of the same; Fig. 3, a side elevation; Fig. 4, a plan; Fig. 5, a longitudinal vertical section; Fig. 6, a transverse vertical section in the line 6 6 of Figs. 3, 4, and 5; Fig. 7, a horizontal section of the cutter and one of the cork-holding chucks; Fig. 8, a horizontal section of the grinder.

Similar letters and figures of reference designate corresponding parts in all the figures.

A is a bed-plate, on which is erected a stationary framing B, which contains in its upper part the bearings for the horizontal shaft C, to which at its front end is securely fas tened the intermittently-rotating carrier D, consisting of a circular disk in which are formed in a circle concentric With the shaft C and at equal distances from each other sockets a, (see Figs. 5 and 7,) which constitute bearings for the revolving chucksE. These Serial No. 630,033. (No model.)

chucks consist each of a tube open throughform for the passage through themof the square sticks F of cork and furnished in front of the carrier with a circular ratchet b and at the back of the carrier with a pulley' c and with spring dogs (l to prevent the backward movement of the cork after it is pushed through the chuck from the front. The carrier-shaft C is furnished at its rear end with a spur-gear C', through which it receives an intermittent rotary motion, as hereinafter described.

H e designate the turning or trimming cutter, arranged or located opposite to and behind the rotating carrier. Thiscutter, which surrounds and incloses the work on which it opi erates, is represented-(see Figs. 5, 6, and 7) as consisting of a rotary hollow stock H, having an opening in one side of it, through which is inserted a cu tting-blade e. This cutter being well known to mechanics needs no further description. It is carried on the front end of a shaft H', arranged parallel with the carrier-shaft in bearings in a carriage H which is fitted to run toward and from the rotary carrier in a slideway H on the top of the framing 13.; The cutter-shaft H' is furnished with'a pulley H*, through which it receives rotary motion from any suitable driving-belt. The said shaft is hollow, as shown in Fig. 7, for the passage through it of a stationary rod f, (see Figs. 4, 5, and 7,) which is firmly held in a'fixed bridge f', bolted on the top of the framing B, behind the cutter-carriage. Thepurpose of this rod will be hereinafter explained.

I is a rotary grinder located opposite to and behind the rotary carrier D on a shaft I', arranged parallel with the carrier-shaft in bearings in a journal-box stand 1 which is supported on a carriage 1 which is fitted to run toward and from the rotary carrier in a slideway 1 on the top of the framing B. The said grinder consists of a grindstone or emerywheel having its profile corresponding with the profile of the corks to be cut. If the corks to be cut are to be taper, the grinder will have a corresponding but reverse taper. The

shaft I' of the said grinder is furnished with a pulley I*, through which it derives rotary notion from any suitable driving-belt. On' one side of this grinde: there is, as shown in Figs. 45, 6, and 8, a holder J, in which the ends F' of the sticks F, which protrude through the backs of the chucks, as shown in Figs. 3 and 4, and which have been cut to the shape of corks, are received and contained during the grindin g operation. The said hold er consists of a socket the interior of which is substantially of the same form as the cork to be ground, but large enough for the cork to rotate freely within it, the said socket having a 1atera1 opening, as shown at j in Fig. 6, so that the periphery of the grinder may enter within it. The said socket is provided with a stern J', which is received within a stock J 2 on the carriage 1 and secured therein by a set-screw j', which provides for the adjustment of the socket J' or holder to the rotary grinder.

The j ournal-box stand 1 is ad j ustable backward and forward on the carriage 1 as provided for by fastening-bolts g g, passing through slots, as shown in Fig. 4, for the purpose of ad j ustin g the grinder toward and from the rotary carrier and in relation to the corkholder J. The said stand I is also adjustable laterally, as provided for by bolts h, passing through slots, and by an adjusting-screw 'i between it and the carriage 1 for the purpose of adjusting the said stand laterally to place the grinder I and the holder J at-a proper distance froni the cutter-shaft H'-that is to say, with the center of the cutter-shaftiand the center of the holder J at a distance apart corresponding with the space between the chucks in the rotary carrier' so that while the stick of cork in one chuck nay be opposite to the grinder the stick in the next chuck in advance of it in the direction of the rotation of the carrier may be opposite the holder J of the grinder. In the rear end of the holder J, which is` closed, there is loosely pivoted a pin j on the inner end of which there are spikes or teethj (see Fig. 8,) which enter the end of the stick of cork which is received within the holder, the said pin se'ving as a pivot for the end of the stick while it is turned in the said holder to present its entire circunference to the grinder and so serviug to keep the sides of the tapered portion of the stick from being pressed against the opposite side of the holder by the action of the grinder.

For the purpose of forcing the cutter-carriage 11 and the grinder-carriage 1 forward to receive the ends of the sticks F as the said sticks are successively presented opposite to the cutter and to the holder J of the grinder there are located behind the said carriages two canis H and 1 one for each carriage. The cutter-carriagc cam 11 is on an upright shaft H which derives rotary inotion through miter-gears k' from the horizontal main shaft K, which works in bearings on the bedstens of the said yokes, which work through fixed guides l Z on the framing A, are screwthreaded to receive stop-nuts l P which are adjustable in front of the said guides and which serve, by coning'in contact with the said guides, as stops to the backward movement of the cutter and grinder carriages.

At a distance below the grinder there is a rotary cutter L, which may be either sharpedged or saw-toothed for the purpose of cutting off the turned and ground portions F' of the sticks F, which when cut off constitute the corks. The shaft L' of this cutter runs in bearings in a swinging frarne L affixed to a rock-shaft L which is supported in bearings in brackets m on the framing B and which is furnished with an arm L connected with the yoke L of a cam L on the main shaft K, the said cam once during every revolution of the said shaft swinging the cutter across the position occupied by a stick F in one of the chucks a, while others of the said chucks are respectively one opposite the cutter and the other opposite the holder of the grinder. A spring L is applied' to another arin L of the rock-shaft for the purpose of drawing back the swingiug cutter-frane L and so preventin g the cutter from interfering with the rotation of the carrier. The cuttershaft L' is furnished with a pulley L*, through which it receives motion from any suitable driving-belt.

The intermittent rotary notion of the carrier is produced by a cam N on the nain shaft K, the said cam acting on an elbow-lever N', (see Figs. 2, 3, and 5,) Working on a fixed fulcrun-pi K Secured in the training B, and being connected by a link N of adjustable length with a double lever N working on a fixed stud 11, which is 'Secured in the framing. This lever N carres a spring-pressed pawl N which engages with a ratchet-wheel N which is fast to a spur-gear N turning on the said stud ll. This spur-wheel gears with the spur-gear C' on the carrier-shaft C, and so dri-ves the carrier. The relative sizes of the gears N and C' and the number of teeth in the ratchet-wheel N are so proportioned that the carrier makes one movement corresponding with the distance between its chucks for every revolution of the main shaft K.

.In order that the carrier in com pletin g each intermittent rotary movement may not be carried by its monentum beyond the point at IOO IIO

which its chucks are inproper relation to the cutter, the grinder, and the saw, there are provided on the carrier, between the chucks, one for each chuck, stop projections n for the arrest of the carrier by the front end of a stoplever P, Figs. 3, 5, and '6, which works on a fixed fulcrum P' in a bracket P, secured to the framing B, and the rear end of which overlies the back of the gear Ic" on the upright shaft H whereon there is provided a can P which at the proper time before each movement of the carrier lifts the rear end of the said lever and trips it from the projection 'n on the carrier with which it had been engaged. At all times but while tripped, as above described, the front end of the stoplever is held up to the periphery of the carrier by a spring n', connecting the said lever with the framing. To ease the stoppage of the carrier and prevent shocks, the front end of the stop-lever is fitted with a facing-piece 71 of metal, behind which there is applied, as shown in Fig. 6, in a dovetail recess in the lever, a small india-rubber cushion-block In front of the carrier there is set up on the bed-plate A a stationary standard Q, a portion of which is represented of open circular form substantially conforming to the carrier. To this frane, as shown in Fig. 1, a springpawl s is secured in such position that when `the carrier is stationary the said pawl en gages with the ratchet wheel b of that chuck E which is opposite the rotary cutter H e, and so prevents the rotation of that chuck while the said cutter is in'operation on the end of the stick therein. The said standard Q has also on it stands or brackets Q', in which are secured the fixed axles q 'r of guide-pulleys q' r', by which a suitably-driven belt R is conducted to run in contact with one or more of the pulleys c of the chucks, but always in contact with the pulley of that chuck which is opposite the grinder, for the purpose of giving rotary motion to the stick in that chuck during the grinding operation. In Fig. 1 the said belt is represen ted in bold dotted Outline as running on the pulleys of two chucks; but that is immaterial so far as the invention is concerned.

Secured on the front of the framing B, behind the carrier, at a point which the: chucks pass on their way to the cutter, there is a fixed gage t, up to which the sticks placed in the chucks are pushed by an attendant as the chucks have severally been brought opposite the said gage by the rotation of the carrier; This gage determines the proper length of the stick to be protruded through the chucks for the fornation of the corks.

Having now described in detail the several parts of the machine and their operation, I

will describe very briefly the operation of cutting corks in the machine.

A stick of cork F of as great length as can be obtained or can be Conveniently manipulated and of suitable thickness is placed in each chuck by an attendant, and as the chucks are brought in succession by the move- .ment of the carrier opposite the gage tthe attendant pushes it forward up to the said gage. The successivo movements of the carrier bring one soprotruding stick oppositethe cutter, another opposite the holder of the grinder, and another in proxirnity to the saw L. The chuck opposite the cutter has its ratchet so engaged by the spring-pawl as to `be prevented from turning in the direction in which has been previously turned is ground,

thechuck opposite the grinder then having its pulley opposite the belt R, giving the stick the necessary rotary motion for grinding. At the same time the saw L is moved by its cam L across the previously turned and ground stick which is opposite to it and the said portion is cut off as a complete cork ready for use. Before the next movement of 'the carrier the rotary cutter H e, the grinder,

and the saw are drawn back to pernit such movement, fresh sticks being supplied to the chucks as fast as the precedin g ones are completely cut up.

During the above-described operation the sticks are held in the chucks by the dogs d securely enough to prevent them from being pulled back by the rotary cutter H e and the grinder during their receding movements. When, however, the stick is cut up so short that no considerable portion of it may remain in the body of the chuck, the grasp 'of the dogs might not be sufficient to retain it, and it is for that purpose that the stationary'rod f is provided running through the cuttershaft. In case there should be any tendency of the cut portion of the stick to remain in the cutter when the latter moves back it will be expelled by the said rod as the cutter moves back. i

Every stick is subjected to the above-described Operations of the rotary cutter, the grinder, andthe saw until there is only left of it a portion of insufficient length to make a cork, the said portion being pushed from the chuck by the insertion of the next .stick thereinto. r I

It is obvious that there might be two grinders like that represented arranged between the rotating cutter H e 'and the cutting-off saw L, the said grinders, one coarser and the other finer, being at such distances apart corresponding with the distance between the chucks that the first one or that nearest the IOO IIO

cutter might be Operating on the cork just trimmed by the cutter, while the other one would be in operation on the one previously ground by the first one.

This machine produces corks with great rapidity and with much less waste than is involved in the ordinary process of cutting corks, which consists in first cutting blanks from the sheet of cork and afterward trimming them to the required conical form.

It is obvious that a machine such as I have hereinabove described is capable of producing bungs, plugs, pegs, or other articles of wood or other material than corks, involving the same Operations in their production, and I should consider such a machine for cutting such articles as within the scope of my invention.
